A textured surface appears slanted about a vertical axis when the image in one eye is horizontally enlarged relative to the image in the other eye. The surface appears slanted in the opposite direction when the same image is vertically enlarged. Two superimposed textured surfaces with different horizontal size disparities appear as two surfaces that differ in slant. Superimposed textured surfac...

In this paper we focus on large-scale IS implementation using the lens of absorptive capacity. Our case study concentrates on the double loop learning process that occurs over the implementation phase of ERP which we depict as a series of learning cycles. From this perspective, ERP implementation is best viewed not as a one-time process but rather as a series of implementation and practical use...

Evolutionary processes of natural selection may be expected to leave their mark on age patterns of survival and reproduction. Demographic theory includes three main strands--mutation accumulation, stochastic vitality, and optimal life histories. This paper reviews the three strands and, concentrating on mutation accumulation, extends a mathematical result with broad implications concerning the ...

The main changes of new capitalism concern mainly two spheres: the new technological paradigm and valorization process and the importance of finance. The main feature of the prevailing finance-led growth regime during the first decade of new millennium is then presented. In this perspective, particular attention is given to the analysis of the evolution and the logic characterizing mergers and ...

Micro data over the life cycle shows different patterns of consumption for housing and non-housing goods: the consumption profile of non-housing goods is hump-shaped while the consumption profile for housing first increases monotonically and then flattens out. These patterns hold true at each consumption quartile. This paper develops a quantitative, dynamic general equilibrium model of life-cyc...

This paper presents a sequential model suited to analyze transitions between equilibria. Disequilibrium dynamics are obtained from a standard monopolistic competition model, by introducing a sequential structure and reasonable hypotheses about technology, finance constraints, expectation formation, and the wage setting mechanism. The response to shocks crucially depends on the institutional fea...

Racial differences in wealth ownership are among the most extreme and persistent forms of stratification in the United States, but the factors that contribute to this inequality are unclear. One potentially important contributing factor is family background. It is a critical determinant of attainment, and both childhood family resources and family structure vary racially. This article reports t...

...If, as is sometimes supposed, science consisted in nothing but the laborious accumulation of facts, it would soon come to a standstill, crushed, as it were, under its own weight...The suggestion of a new idea, or the detection of a law, supersedes much that has previously been a burden on the memory, and by introducing order and coherence facilitates the retention of the remainder in an avai...

In this paper we derive conditions on the internal wear process under which the resulting time-to-failure model will be of the simple collapsible form (Oakes, 1995, Duchesne and Lawless, 2000) when the usage accumulation history is available. We suppose that failure occurs when internal wear crosses a certain threshold and/or a traumatic event causes the item to fail (Cox, 1999 and Bagdonavičiu...
